Colibacillosis in lambs is associated to type I heat-stable enterotoxin in a farm in São Paulo State, Brazil

Abstract

Twenty seven (48.2%) culture supernatants of 56 Escherichia coli isolated from diarrheic lamb feces (7 to 10 days old) in São Paulo State, Brazil, presented

Detection of virulence factors and antimicrobial resistance patterns in shiga toxin-producing Escherichia coli isolates from sheep

“…Sheep can act as main disseminators of this pathogen in animal-derived food products and water and as direct transmitters to humans, however, studies on the distribution of CNF-1 in STEC isolates from healthy sheep are limited. In this study we found the presence of cnf1 gene in 32.2% (29/90) of STEC isolates from healthy sheep, which is higher than reported in previous studies (Orden et al 2007, Aragão et al 2012. The STEC isolates carrying the cnf1 gene were widely reported in relation to HUS outbreaks in humans (Dozois et al 1997), and our study confirmed the importance of this virulence factor of STEC isolates from sheep in the state of Goiás as a potential threat to human health.…”
